A new study shows that nickel oxide superconductors, which conduct electricity with no loss at higher temperatures than conventional superconductors do, contain a type of quantum matter called charge density waves, or CDWs, that can accompany superconductivity.

The presence of CDWs shows that these recently discovered , also known as nickelates, are capable of forming correlated states— electron soups that can host a variety of quantum phases, including superconductivity, researchers from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University reported in Nature Physics today.

“Unlike in any other superconductor we know about, CDWs appear even before we dope the material by replacing some atoms with others to change the number of electrons that are free to move around,” said Wei-Sheng Lee, a SLAC lead scientist and investigator with the Stanford Institute for Materials and Energy Science (SIMES) who led the study.

OAKLAND, Calif. July 25 (Reuters) — U.S. chipmaker Intel Corp (INTC.O) said on Monday it will produce chips for Taiwan’s MediaTek Inc (2454.TW), one of the world’s largest chip design firms.

The manufacturing arrangement is one of the most significant deals Intel has announced since it launched its so-called foundry business early last year.

A foundry business builds chips that other companies design and Taiwan Semiconductor Manufacturing Co (TSMC) (2330.TW) is the top player in that space. Intel has mainly built chips it designed itself.

If radars wore pants, a lot of them would still be sporting bell-bottoms.

Significant aspects of haven’t fundamentally changed since the 1970s, said Kurt Sorensen, a senior manager who oversees the development of high-performance radio frequency imaging technologies at Sandia National Laboratories. Like a record player, most military-grade systems are still analog.

Now, Sandia is giving radar a major digital makeover. Researchers are working to replace legacy analog radars commonly used by the military with a new, digital, software-defined system called Multi-Mission Radio Frequency Architecture. The overhauled design promises U.S. warfighters unprecedented flexibility and performance during intelligence, surveillance and reconnaissance operations, even against sophisticated adversaries.

Sunlight sparkling on water evokes the rich phenomena of liquid-light interaction, spanning spatial and temporal scales. While the dynamics of liquids have fascinated researchers for decades, the rise of neuromorphic computing has sparked significant efforts to develop new, unconventional computational schemes based on recurrent neural networks, crucial to supporting wide range of modern technological applications, such as pattern recognition and autonomous driving. As biological neurons also rely on a liquid environment, a convergence may be attained by bringing nanoscale nonlinear fluid dynamics to neuromorphic computing.

Researchers from University of California San Diego recently proposed a novel paradigm where liquids, which usually do not strongly interact with light on a micro-or nanoscale, support significant nonlinear response to optical fields. As reported in Advanced Photonics, the researchers predict a substantial light-liquid interaction effect through a proposed nanoscale gold patch operating as an optical heater and generating thickness changes in a covering the waveguide.

The liquid film functions as an . Here’s how it works: Light in the waveguide affects the geometry of the liquid surface, while changes in the shape of the liquid surface affect the properties of the optical mode in the waveguide, thus constituting a mutual coupling between the optical mode and the liquid film. Importantly, as the liquid geometry changes, the properties of the optical mode undergo a nonlinear response; after the optical pulse stops, the magnitude of liquid film’s deformation indicates the power of the previous optical pulse.

What if your running shoes could really adapt to your feet — and not just in the way that footwear retailers describe to solidify sales. These cutting-edge Protocells Trainers present the fascinating possibilities of wearable living materials that can grow, modify and repair themselves through continuous use.

Shamees Aden has been working with Dr. Martin Hanczyc on these innovative kicks, developing a synthetic biological substance that could be 3D printed to fit the wearer’s feet like gloves. The composite organic fabric would provide surface protection to toes and soles, yet it could also offer support skeletal and muscular. The anatomical tissue of the Protocells Trainers would thicken in areas that experience more pressure, and they could heal their own tears while bottled in a special solution overnight.

We denimheads tend to be a bit nostalgic. That’s one of the reasons we love denim: it’s a constant in the fast-moving world of fashion, something that doesn’t change from one season to the next.

Penn State scientists made a coating that allows conventional textiles used in everyday clothing to patch themselves up. Derived from squid ring teeth, the coating can turn virtually any fabric into a self-healing one. Simply adding water is enough to kick start the repairing process.

Nano research has already revealed the potential of self-cleaning clothes, and now a new study reveals the potential for similar technology in suits that can be used to protect soldiers from chemical or biological attacks.

A U.S. House Intelligence Committee member cautioned that bioweapons using a target’s DNA to kill only that individual are being created. US Representative Jason Crow of Colorado spoke on Friday at the Aspen Security Forum and cautioned Americans not to be too careless about sharing their DNA with private firms due to the impending arrival of the new type of weapon. “You can target a biological weapon that will kill that person or take them off the battlefield or make them inoperable,” Crow said. “You can take someone’s DNA, you know, take their medical profile,” he added.

Given the prevalence of DNA testing services, where customers voluntarily share their genetic mapping with companies to learn more about their ancestry and health, the congressman said it is concerning that these weapons are being developed. Although 23andMe has maintained time and time again that it does not sell its customers’ private information, it is one of many DNA companies that have done so when asked by the police.

As a member of the Senate Armed Services Committee, US Senator Joni Ernst of Iowa claimed that the US’s adversaries may deploy such DNA bioweapons to attack food supply on a large scale. Ernst forewarned that specific animals relied upon by civilians, armies, or towns could be the target of biological weapons, resulting in scarcity and food poverty and weakening populations.
